d Letters Patent No. 83,202, dated October` 20, 1868.

The Schedule referred to in these Letters Patent and making part of the same.

To allwhom 'it may concern:

Be it known that I, LOUIS J. PARSONS, of New Bed ford, in the county of Bristol, in the State of Massachusetts, have invented a new and improved Adjustable Mosquito-Bar Frame; and I do hereby declare' that the following is a full and eXact description thereof, reference being had to the accompanying drawings, and to the lettersof reference marked thereon. I My invention consists' in making a mosquito-bar yframe inparts, so arranged that it may be made to it any-sized window, and so far self-adjusting that it can be put into a window-frame, without removing any part thereof.

Figure 1 is a perspective view of my invention, applied to a window-frame.

Figure 2 is a sectional view, showing the manner in which the frame is put together. l

Fig. 1. A, window-frame; Bl, mosquito-bar frame, in which c, Src., are knees, of metal, or any suitable material; d d d, ferrules; e c1 c, nuts, forming part of' the ferrules; g1 g g, screws, on ends of knees cl, 86o.; h1, handle, by'which to put in and take out the frame.

Fig. 2. B2, mosquito-bar frame,.in which c2 cz c2 are knees; dz d d2, ferrules; c2 e2 c2 nuts, on ends of ferrules; gz gl g2, screws on ends of knees cz, 85e.; h, handles, by which-to insert or remove the frame; il, spiral spring.

Operation.

The various parts of my invention being made as shown, two of the knees having each respectively one of the ferrules, (in the drawings, the short ferrules on the uprights,) firmly secured to it by the end opposite the nut; the other two fer-rules, (in the drawing, the long ones at the top and bottom,) being screwed on in their respective places, with spiral springs placed in them, its operation, novelty, and utility may be noted.

The parts being screwed togetherto the desired height, the loose ends, x x, (see iig. 2,) of the knees are slipped into the ferrules, at top and bottom I,of the frame, till their ends rest upon the spiral springs i2 i2.

The frame is then placed in the window, and the feuules at top and bottom are turned till the sides of the frame touch the' inside of the window-Stiles.

The frame can then be taken out by drawing together the handles h2 h2, till one side will slip past the projection of the window-stile.

The advantages of this invention are, the ease with which it can be put in and taken out, its fitting perfectly close when in, and its adaptability to differentsized windows.

In this invention I do notf claim any device previously invented or patented for mosquito-bar frame, vbut What I claim as my invention, and desire to secure by 'Letters Patent, is-

Ainetallic mosquito-bar frame, in combination with springs and screws, as herein set forth and described,

for the purpose specified.
